About Filesystem

What is Filesystem: Real-Time Sync & Cross-Cloud Security?

Filesystem is a Model Context Protocol (MCP) server built on the mcp-framework, designed to enable real-time synchronization across cloud environments while maintaining robust security measures. It provides a modular architecture for developers to extend functionality through custom tools, ensuring seamless integration with platforms like Claude Desktop.

How to Use Filesystem: Real-Time Sync & Cross-Cloud Security?

To get started:

Install dependencies and build the project using npm commands.
Create custom tools via the CLI (e.g., data processors or API clients) to tailor sync/security workflows.
Deploy locally by configuring absolute paths in Claude Desktop, or publish to npm for broader accessibility.
Test configurations using the built-in development workflow to ensure real-time sync and security protocols function as expected.

Filesystem Features

Key Features of Filesystem: Real-Time Sync & Cross-Cloud Security

Instant Synchronization: Leverages MCP protocols to maintain data parity across multiple cloud platforms in real-time.
Multi-Cloud Security: Implements end-to-end encryption and granular access controls for sensitive data transfers.
Modular Tool System: Extend core functionality with custom tools written in TypeScript, validated via Zod schema enforcement.
Seamless Integration: Works directly with Claude Desktop through configurable server entries, reducing setup friction.
Production-Ready Publishing: Streamlined npm packaging ensures tools are easily distributable for enterprise use.

Use Cases of Filesystem: Real-Time Sync & Cross-Cloud Security

This framework excels in scenarios requiring:

Collaborative Workflows: Teams needing instant access to updated files across AWS, GCP, and Azure environments.
Compliance-Driven Sync: Enterprises handling regulated data that demands audit trails and encryption.
Hybrid Cloud Migration: Organizations transitioning infrastructure while maintaining operational continuity.
Automated Data Processing: Developers building pipelines that require real-time data validation and transformation.

Filesystem FAQ

FAQ from Filesystem: Real-Time Sync & Cross-Cloud Security

Q: Can this work with non-cloud file systems?
A: Yes, but requires configuring custom sync adapters to handle on-premise storage solutions.

Q: How does security work during sync?
A: Data is encrypted in transit and at rest, with permissions managed through MCP's access control lists (ACLs).

Q: Can I use this without Claude Desktop?
A: Absolutely—the CLI tools and server components operate independently of the Claude ecosystem.

Q: What happens if cloud services go offline?
A: The system maintains local state and automatically reconciles changes once connectivity is restored.

A Model Context Protocol (MCP) server built with mcp-framework.

Quick Start

# Install dependencies
npm install

# Build the project
npm run build

Project Structure

filesystem/
├── src/
│   ├── tools/        # MCP Tools
│   │   └── ExampleTool.ts
│   └── index.ts      # Server entry point
├── package.json
└── tsconfig.json

Adding Components

The project comes with an example tool in src/tools/ExampleTool.ts. You can add more tools using the CLI:

# Add a new tool
mcp add tool my-tool

# Example tools you might create:
mcp add tool data-processor
mcp add tool api-client
mcp add tool file-handler

Tool Development

Example tool structure:

import { MCPTool } from "mcp-framework";
import { z } from "zod";

interface MyToolInput {
  message: string;
}

class MyTool extends MCPTool<MyToolInput> {
  name = "my_tool";
  description = "Describes what your tool does";

  schema = {
    message: {
      type: z.string(),
      description: "Description of this input parameter",
    },
  };

  async execute(input: MyToolInput) {
    // Your tool logic here
    return `Processed: ${input.message}`;
  }
}

export default MyTool;

Publishing to npm

Update your package.json:

* Ensure `name` is unique and follows npm naming conventions
* Set appropriate `version`
* Add `description`, `author`, `license`, etc.
* Check `bin` points to the correct entry file

Build and test locally:

npm run build

npm link
filesystem  # Test your CLI locally

Login to npm (create account if necessary):

npm login
Publish your package:

npm publish

After publishing, users can add it to their claude desktop client (read below) or run it with npx
